Which causes objects to have a change in motion?

Energy 

Speed

Size

Force

Which scenario below is the same type of collision as two moving cars crashing into each other?

A golf ball and golf club

A tree falling onto a house

Baseball player hitting a fastball

Stepping on a pair of glasses on the floor

Look at the data for two different materials. Which material has the lowest breaking point?

Material A

Material B

What is changed in the experiment (cause)

What stays the same throughout the investigation

A independent variable is

Data measured (effect)

What is changed in the experiment (cause)

What stays the same throughout the investigation

A controlled variable is

6. There are three types of collisions that tend to happen frequently in soccer:
A) Headers (when a ball makes contact with a head)
B) Collisions between players' heads
C) when players hit the ground.

How would the amount of force on the head compare to the amount of force on the object it collides with, in each system A, B, and C?

In EVERY collision, the peak force on the head would be the SAME as the peak force on the other object in the collision.

In SOME, BUT NOT ALL collisions, the peak force on the head would be the SAME as the peak force on the other object in a collision.

In EVERY collision, the peak force on the head would be DIFFERENT than the peak force on the other object in the collision.

What did we see happen to the different materials as the force applied to them was increased? (Ex. Steel vs coffee stirrers)

The deformation decreased for all materials at the same rate.

The deformation increased for all materials at the same rate.

The deformation increased for all materials but each material had a different rate of deformation.

There was no deformation.

What happens when an object has reached it's elastic limit (its maximum amount of deformation)?

Nothing, it stops changing shape.

It deforms permanently .

It keeps bending.

What are the variables that affect a material's elastic limit? Check all that apply.

Type of Material

Color

Thickness

Shape

Do all objects have the same breaking point?

Yes, all objects break when the same amount of force is applied to them.

No, different objects can withstand different amounts of force.

In a collision at least one object will experience a change in motion.

True

False

A tire company is investigating how different tires impact a car's top speed. They use the same car for each trial they run, but replace the tires each time. For each new set of tires they put on, they run a new trial and record the car's top speed.

Which variable is independent, dependent, and controlled?

Choose from the following:
Top speed of car
Type of tire
Type of car

Based on what you know about collisions, which of the following statements below is most likely correct.

This is likely a fake image - Hard objects like a golf ball are too hard to deform.

This is likely a real image - Although a golf ball feels hard it is capable of deforming.

This could be real, but with a fake ball - Only soft objects are capable of deforming.

A baseball player swings his bat and makes contact with a baseball. Which experiences a greater force?

The bat applies a greater force on the ball.

The ball applies a greater force on the bat.

Neither. They experience the same force.

Cart A with 4 washers collided with Cart B with 2 washer. The peak force recorded for Cart A was 2N. What is the peak force recorded for Cart B?

1N

2N

3N

4N

Below is a gaph of four different materials and the amount of deformation as the force was applied to each object. There is a diagram of the deformation of each object at a force of 4N. Whichdiagram represents Material D tat 4N of force? Explain your answer.
